Steel name: SAE 5140
  Diagram No.: 2875
  Type of diagram: TTE
  SAE: 5140
  Chemical composition in weight %: 0.45% C, 0.77% Mn, 0.35% Si, 0.015% P, 0.013% S,
  0.72% Cr, 0.25% Mo.
  Note: Embrittlement diagram. Temper embrittlement. Austenitizing temperature: 840 ^oC
  (1540 ^oF). Grain size: 7. Figures beside points represent increase in transition
  temperature (^oF) based on transition temperatures of specimens tempered at 1260 ^oF
  for 5 s. Figures in parentheses are the average hardness of the speicmens in that series.
